This mixture of .o-il with the vapor causes a lowering o iiternperature to such an extent that complete combustion is impossibleand depositi'on of carbon results In the vpresent invention, the oilpasses into a retortwhich is maintained at a very hightemperature and isimmediately vapor-' ized. A uniform temperature is maintained 40throughout the retort and mixture of oil and vapor is prevented as theoil is vaporized as soon as it passes into the retort. I This gives avapor which burns Without deposi tion of carbon. The burner constructionabove described is shown but not claimed in my co-pending application,and forms the subject matter of the present application.

An object of the invention is-the provision of an oilburner in which theoil will be completely and properly vaporized before] being admitted tothe burner A further object is the provisionv of a burner casing inwhich the vaporizing retort ted lines 14, in Figure 1 of the drawings.

The provision of a retortarranged entirely at the front of the casing, forwardly of the pointWhere the flame strikes the Walls of the cas- ,ing insures a temperatureWithin the-retort sufficiently high to immediately vaporize the oil;vThis provides a fuel Whichwill burn properly without deposition ofcarbon.

' It will be apparent that the vaporizing chamber or retort ishighly,heated by the flame'from the burner and theoil is vaporized as soon asit' .reaches ,the retort. There is no oil present at any time ithin theretort and mixture of oil -and vapor is pre-" vented. JIn addition, theoil enters at the bottom and the vapor is removed at the topq so I as bypressure. Iheretort is;pr0,v ided,Wil h (I i The vapor being lighterthan the oil, flows freely to the top and there is no tendency to carryoil into the burner mixed with the vapor. A substantially uniformtemperacasing and disposed forwardly of the point where the flamestrikes the walls provides a burner by means of which a highertemperature may be obtained than in a construction where the retortextends rearwardly of the point where the flame strikes the walls.

As stated, the deposition of carbon is reduced to a minimum and thelength of time that a burner may be operated without stopping to removecarbon from the burner casing is materially increased.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresortedto without departing from the spirit of my invention or thescope of the subjoined claims. i A

Having thus described my invention, I claim:

v 1. A burner comprising a casing forming a combustion chamber, a nozzlemounted adjacent the rear of said casing, a vaporizing retortsurrounding said casing and terminating at substantially the point wherethe flame from said nozzle strikes the wall of said casing, a feed pipeconnected to said retort exteriorly of said casing, and a pipeconnecting said retort and said nozzle, said pipe extending exteriorlyof said casing.

2. A burner comprising a casing forming nozzle against the wall of the acombustion chamber, the rear of said casing being open for theintroduction of air, the forward end of said casing being formedof'double walls to provide a vaporizing retort, a feed pipe connected tosaid retort exteriorly of said casing, a. nozzle mounted in the rear ofsaid combustion chamber,- a pipe connecting said retort to said nozzle,said pipe extending exteriorly of said casing, and means for directingthe flame from said combustion chamber adjacent said retort.

3. A burner comprising a casing forming a combustion chamber, the rearend of said casing being open, the forward end of said casing beingreduced and provided with spaced walls to form a vaporizing retort, a

feed pipe connected to said retort exteriorly of said casing, a nozzlearranged adjacent the rear of said combustion chamber, and a pipeconnecting said retort and said nozzle,

said pipe extending exteriorly of said ca'sing, said retort terminatingat substantially the point where the flame fromsaid nozzle strikes thewall of the combustion chamber.

4. A burner comprising a casing forming a combustion chamber, a nozzlearranged adjacent the rear of said combustion cham: ber, the 'walls ofsaid casing converging vertically forwardly of said nozzle anddiverginghorizontally to provide a broad outlet of restricted height, avaporizing retort surrounding the forwardend of said casing, said retortterminating at substantially the point where the flame from said nozzlestrikes the wall of the combustion chamber, means. for conveying fuel tosaid retort, and means for conveying vaporized fuel from said retort tosaid nozzle.

In testimony whereof I aflix my signature in presence of two witnesses.
